Component
plugins/field-grid-dropdown/src/grid.ts (FieldGridDropdown)
Problem
Recent changes in core introduced FieldDropdown.SEPARATOR as a valid MenuOption.
PR #2504 made changes to ensure that FieldGridDropdown's class Grid will compile and ignore these separators.
Request
Including separators in the list of items for the FieldGridDropdown should do something useful—perhaps creating a horizontal or vertical separator in the grid depending on the position of the SEPARATOR item in the list of options.
